Product Description
The VIA PFM is a highly advanced 400 W AC-DC converter
operating from a rectiï¬ed universal AC input which delivers an
isolated and regulated Safety Extra Low Voltage (SELV) 48 V
secondary output.
This unique, ultra-low proï¬le module incorporates AC-DC
conversion, integrated ï¬ltering and transient surge protection
in a chassis mount or PCB mount form factor.
The VIA PFM enables a versatile two-sided thermal strategy
which greatly simpliï¬es thermal design challenges.
When combined with downstream Vicor DC-DC conversion
components and regulators, the VIA PFM allows the Power
Design Engineer to employ a simple, low-proï¬le design which
will differentiate his end-system without compromising on
cost or performance metrics.
